The 2026 fixed-rate cliff: what to do 6 months before your rate expires

9 July 2026 · Refinancing · 5 min read

Every month, tens of thousands of Australian home loans roll off a low fixed rate onto their lender's revert rate — almost always one of the most expensive rates the bank offers. The borrowers who plan the transition six months out routinely save hundreds of dollars a month over those who let it happen on autopilot. Here is exactly how to be in the first group.

What the ‘fixed-rate cliff’ actually is

When your fixed term ends, your loan does not stay at the fixed rate, and it does not automatically move to the bank's sharpest variable deal. It reverts to a standard variable rate the lender relies on you not noticing. The gap between that revert rate and a competitive market rate is where the money quietly leaks out of your budget.

A worked example

Say you have a $600,000 loan with 27 years remaining, rolling off a fixed rate onto a 7.4% revert rate, at a time when competitive rates are closer to 6.1%.

• At 7.4%, repayments are roughly $4,180 a month.
• At 6.1%, they are roughly $3,700 a month.
• That is about $480 a month — over $5,700 a year — for exactly the same debt.

Six months out: know your numbers

Dig out your loan documents and write down three things: your fixed-rate expiry date, the revert rate you will drop to, and your current balance and remaining term. Put the expiry date in your calendar with a reminder set six months earlier. This is the single most valuable ten minutes in the whole process — most people miss the window simply because nobody told them the date mattered.

Three months out: get review-ready

Assessments take longer than people expect. Gather your latest loan statement, recent payslips (or, if you are self-employed, your last two years of returns) and a realistic sense of your property's value. A licensed mortgage broker can compare staying, repricing and switching across multiple lenders in one conversation — lenders themselves only ever show you their own book. Starting now leaves room for valuations and paperwork without racing the clock.

One month out: decide, don't drift

You have three real choices, and ‘do nothing’ is the most expensive one:

• Stay and reprice — ask your current lender for their best retention rate. Sometimes it is competitive; often it is not.
• Split — fix part and keep part variable, to balance certainty with flexibility.
• Switch — refinance to a lender offering a materially better rate or structure.

Whatever you choose, make it an active decision before the revert rate kicks in.

Three mistakes that cost the most

• Finding out after the fact. By the time the higher repayment hits your account, you have already paid the lazy tax for a month or more.
• Only asking your own bank. Loyalty is rarely rewarded at revert time.
• Assuming refinancing is a hassle. With your documents ready, a switch is often faster and simpler than people fear.

Quick questions

Does refinancing hurt my credit? A single application makes a minor, short-lived mark; the ongoing saving usually dwarfs it. It is scattergun applications across many lenders that do the damage.

What if my property value dropped? It affects your loan-to-value ratio and the rates you qualify for, but there are still options worth reviewing rather than assuming the worst.

How early is too early? You generally cannot lock a new rate months ahead, but you can have everything ready so you move the day it makes sense.
